In the title cadmium(II) coordination polymer, poly[tri-mu(4)-adipato-bis(2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene-kappa(2)N(7),N(8))tricadmium(II)], Cd(3)(C(6)H(8)O(4))(3)(C(19)H(12)N(4))(2), one of the Cd atoms is in a distorted pentagonal bipyramidal coordination environment, surrounded by five O atoms from three adipate (adip) ligands and two N atoms from one 2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene (L) ligand. A second Cd atom occupies an inversion center and is coordinated by six O atoms from six adip ligands in a distorted octahedral geometry. The carboxylate ends of the adip ligands link Cd(II) atoms to form unique trinuclear Cd(II) clusters, which are further bridged by the adip linkers to produce a two-dimensional layer structure. Topologically, each trinuclear Cd(II) cluster is connected to four others through six adip ligands, thus resulting in a unique two-dimensional four-connected framework of (4,4)-topology. This work may help the development of the coordination chemistry of 1,10-phenanthroline derivatives.
在标题化合物镉（II）配位聚合物聚[三-μ（4）-己二酸根-双（2-苯基-1H-1,3,7,8-四氮杂环戊并[1]菲咯啉-κ（2）N（7），N（8））三镉（II）]，[Cd（3）（C（6）H（8）O（4））（3）（C（19）H（12）N（4））（2）]（n）中，其中一个镉原子处于扭曲的五角双锥配位环境中，被来自三个己二酸根（adip）配体的五个氧原子和来自一个2-苯基-1H-1,3,7,8-四氮杂环戊并[1]菲咯啉（L）配体的两个氮原子所包围。第二个镉原子占据一个对称中心，并由来自六个己二酸根配体的六个氧原子以扭曲的八面体几何构型配位。己二酸根配体的羧基末端连接镉（II）原子形成独特的三核镉（II）簇，这些簇进一步通过己二酸根连接体桥连以产生二维层状结构。从拓扑学角度看，每个三核镉（II）簇通过六个己二酸根配体与另外四个相连，从而形成一个独特的二维（4,4）拓扑的四连接框架。这项工作可能有助于1,10-菲咯啉衍生物配位化学的发展。
